. Key Components
Feeding Hopper: A metal hopper where maize cobs are fed into the machine, usually designed for gravity flow.
Shelling Drum/Rotor: A cylindrical drum equipped with spikes, radial bars, or lugs that rotate at high speed to detach kernels from the cob via impact and friction.
Concave/Sieve: A perforated, semi-circular screen that sits beneath the drum. It allows only the detached kernels to pass through while keeping the cobs inside.
Blower/Fan: An in-built fan that blows away lighter debris and chaff, ensuring clean maize grains are produced.
Main Frame: A welded iron/steel frame that holds the components, providing stability.
Power Source: Most locally assembled models are powered by a 5.5 to 7.5hp gasoline (petrol) or diesel engine, though electric motor variants are also common
